The Mion River Battle

Saber, Lancer, and Rider fight to stop Caster's demon from reaching the shore. However, it regenerates at an astounding pace, making it difficult to destroy. Kirei and Risei discuss plans to cover up the incident, while Archer and Tokiomi watch the battle aboard Archer's aircraft, the Vimana. Tokiomi pleads with Archer to assist in destroying Caster, but the latter refuses after 'sacrificing' four of his weapons to damage the beast. A crowd of bystanders begins to gather along the river and a pair of F-15 jets are caught in the battle while patrolling the area. Berserker appears, takes control of one of the jets, and engages in aerial combat with Archer's Vimana while the other jet is consumed by Caster's demon. Kariya confronts Tokiomi about his treatment of Sakura, and is enraged when Tokiomi simply dismisses his wife and daughters as 'rabble'. He attacks him as Kirei watches their fight from afar. Uryuu, watching from the bank, is sniped by Kiritsugu and dies. Caster senses the death of his Master and vows to fulfill the promise he made to him. Kiritsugu deduces that Caster's demon is an immortal being that will regenerate itself if even a small piece of it is left, hence, it must be destroyed in a single, powerful attack. He reveals that Saber possesses a Noble Phantasm which can achieve this.
